thank you. Based upon what you say, there should not be an obstacle to a remortgage or indeed future sale providing the work itself is not a risk to the building. Building regulations can only be enforced for a period of 12 months from the date of completion by the local authority unless the local authority can show that the work in question is dangerous.
The solicitors are required to comply with the rules set out in the lenders Handbook and I am including a link to the same below. In particular, you will want to look at section 5.5.
If you were to look at the same, you will note that it provides as follows (remember this is written to the instructed solicitor not you as the customer - ie. this is what the solicitor must do):
If there is evidence of such a breach or matter but in your professional judgment there is no reasonable prospect of enforcement action and, following reasonable enquiries, you are satisfied that the title is good and marketable and you can provide an unqualified certificate of title, we will not insist on indemnity insurance and you may proceed.
accordingly, the solicitor may want to satisfy themselves that the work in question is not likely to be dangerous and therefore may request evidence that it was completed by an registered or insured builder or that a surveyor has at some point in the past inspected the work under a building survey but subject to this, providing the solicitor is satisfied that the work is not likely to be dangerous, given what we discussed above, building regulations cannot be enforced after a period of 12 months and accordingly, there is no requirement to provide indemnity insurance.
in terms of any future remortgage, in the assumption the solicitors are not appointed by the bank as some form of product incentive which pays for legal costs, it would be sensible when appointing a solicitor to highlight this issue before instructing them and checking how the solicitor would approach the matter. Essentially there is only likely to be an issue if the solicitor in question decides to make an issue of it. Accordingly you would ideally look to appoint a pragmatic solicitor pf which most (but not all) are.
